SPECIFICATION forming: part of Letters Patent No. 735,483, dated August 4, 1903.

Q Application filed June 8, 1901. Serial No. 63,695. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE CHAR ES ESK- HOLME, a citizen of the United States, and a resident of the borough ofBrooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hydrocarbon Mixers and Regulators, of which the following is a specification. My invention relates to means for automatically mixing and distributing charges of hydrocarbons and air for engines and the like. i

The object of the invention is the production of automatic mixing and distributing regulators of simple construction which will maintain correct relations between the volumes of hydrocarbons and air, when applied to engines which run with variable speeds. Figure 1 shows a partial vertical section of I my automatic mixer and regulator on the line Fig. 2represents a top plan view of the same. Fig. I is a plan view of the mixing-chamber with the hood and inletvalve removed. Fig. 4 shows an elevation of Fig. 3. Fig. 5 is a section of Fig. 3 on the line 00 m.

. The in ention is shownto comprise the receptacle A with the valve-chamber B, on the top of which is secured the hood C. A valve D, with openings d, works over ports I) in the valve-chamber B and extends to d, where it makes a joint with theupper portion c of the Fig. 7 shows an ole- Fig. 8 is a top plan view of Fig. 9 represents an Fig. 13 is an eleva-- Fig. l ishows a plan view hood 0. From the valve D extends the arm d terminating in the ball d which makes a ball-and-socket joint with the link E. I11 the valve-chamber B is screwed the pin F, which extends up through the hollow vertical extension (1 of the valve D. The ports bin the airvalve chamber B connect with the passages 19 The fuel-chamber G is screwed into the upper portion a of the hood 0 which contains the openings 0 and this chamber carries the fuel-valve H and is cored at g to provide an annular chamber for the influx of the hydrocarbon. A threaded boss 9 extends from G, against which is secured the fuel-supply pipe I by means of the nut I. A central passage 9 in the boss 9 leads to the cavity g. A cross-head J is secured on the valve H with the split nut j, which latter clamps the said valve H, by means of which the position of the valve can be varied.

A cylinder is shown at K with its piston L, carrying the packing Z, secured against the said piston with the follower-plate Z. The piston-rod N is screwed into the piston and extends through the bonnet M and its projecting barrel m. The bonnet is pierced with holes m A collar 0 is screwed on the piston-rod N to adjust the action of the spring P between the said collar 0 and the bottom of the projecting barrel m of the bonnet M. A forked bell-crank Q Q fits between the collars 1- of the cross-head R,

The forked bellin bearings U, extending from a stand V with an annular base 12, which is fastened to the sleeve m of the bonnet M by means of the screw '0 The levers Y Z 'and'forked bellcrank Q Q are fastened to the shaft T. The lever Y works the link E and the lever Z carries a pin 2, to which ishooked the detachable link Z the latter being worked by the handle-bar 2 when the said link Z is in operative position on the pin 2 of the lever Z. \Vhen it is desired to disengage the link Z from the pin a, a secondary link .2 j ournaled to the handle-bar e engages a pin 2 on the link 2 The link E by its movement turns the valve D, allowing more or less port-opening for air into the receptacle A. When the forked bell-crank Q Q is moved by the piston L, it transmits its motion to the toggle-links and 7'3, respectively j ournaled to the crosshead J and chamber H, by means of which the valve 11 is moved for the admission of the hydrocarbon. The cross-head Q is adjustably clamped on the arm Q of the bell crank head Q in proper operative positions on the forked bell-crank Q Q to obtain the proper lift of the valve H with the toggle-joint connection for varying grades of hydrocarbons.

In the receptacle A and secured to the valve-chamber B there is a deflecting-cone B with a central opening I), under which are located a series of wire screens W with rings which latter secure free passages through the said screens. The combination of rings and screens forms a vaporizer, and under the said vaporizer is located a deflector X, in-

clined outwardly from its center, with openings .00 near the circumference thereof and beyond the central opening b of the deflecting-cone B A second series of screens \V are situated below the deflector X, and under the said second series of screens is placed the deflector X inclined inwardly from its circumference, with a central opening 42 The four elements comprising the screens W, deflector X, screens W and deflector X constitute a combination which can be multiplied a number of times, as shown in the drawings.

It will be noticed that all the elements in the receptacle between the valve-chamber and the base connection, with the exception of the rings and screens, only butt against each other and can be easily removed and cleaned.

' Under the lowest deflector X is placed a bottom hood X with openings 00, the said hood resting upon the base connection A. The hood X contains lugs or ears m which constitute supports for the deflector X resting thereon.

The base connection A supports the receptacle A and cylinder K and is tapped for the pipe k and nipple 10 leading to piping k which latter extends to the exploding-chamber of the engine.

The base connection A contains the openings a, which connect with the chamber a from the top of which ports at lead to the bottom of the hood The bottom portion of the chamber a constitutes a reservoir for collecting debris to be discharged by a petcock 0?.

inthe bottom connection A runs from a cen- A central longitudinal channel a tral opening a? tozan annular channel a opening into the cylinder K.

To automatically operate the invention, the cross heads J Q R and collar 0 are properly adjusted, the link Z thrown outv of gear, and the hydrocarbon fed through the pipe I, whence it will run down the needlevalve H and on the pin F, from which it finds its way through the ports I) of the valvechamber B. Air enters through the ports d of the valve D, mixing with the hydrocarbon,

and both travel down the receptacle A through the combinations of screens and deflectors, thereby vaporizingthe charge and percolating through the holes :13 of the lower hood X and the openings at of the base connection A, after which the charge passes through the chamber a in the bottom connection and reaches the opening a, which leads to the channel a from whence the charge, by way of the annular'opening a enters the cylinder K and is finally drawn into the piping k The lower portion of the chamber a collects the debris, which escapes by opening the cock a The piston of the hydrocarbon-engine (not shown) tends to pull down the piston L by virtue of internal suction and atmospheric pressure through the holes m which actuates the valves D and H, and this distance increases with the increased number of strokes of the engine, controlling thereby the volumes of air and hydrocarbons admitted to the receptacle A, and when the engine slows up the spring P pulls up the piston L and closes the valves D and H.
